Atrioventricular transfer area and escape rhythm

When the excitement in the sinoatrial node or the atrium cannot be transmitted to the atrioventricular transfer area on time, and the interval exceeds the time limit of the autonomic cycle of the potential pacing points in the tissue of the transfer area, this potential pacing point is issued with impulses, resulting An ectopic heartbeat is called a junctional escape. 3 or more consecutive junctional escape rhythms constitute a junctional escape rhythm.
